I'll definitely prefer Milan (Malpensa) over Rome, especially in the high season. Immigration lines at Rome airport are atrocious.
Better yet, plan your routes to enter Schengen area outside Italy (stopover in Munchen, Warsaw and Zurich are nice in my experience; Frankfurt and Amsterdam too huge to be nice), then connect to Milan.
Most of other airports are either farily small or packed with tourists, I guess.
